Video Poker Royal Flush Calculator: Chasing the Jackpot

The royal flush is video poker's ultimate prize—800 coins for max bet, changing a negative-EV game into a positive one. Our calculator shows royal flush probability, how hold decisions affect your chances, and the math behind chasing that elusive hand.

What Is a Royal Flush?

A royal flush is A-K-Q-J-10 of the same suit—the highest possible poker hand. In video poker, it pays 800:1 with max bet (4000 coins for 5 coins wagered) but only 250:1 with lower bets. This jackpot makes max betting essential.

Quick Answer: Royal flush probability: 1 in 40,391 hands (optimal play). Pays 800:1 max bet, 250:1 otherwise. Contributes ~2% to game's return. Never chase royals by breaking good hands. Optimal strategy already maximizes royal chances. Max bet mandatory—250:1 payout destroys expected value.

Royal Flush Probability

Base Odds (5-Card Deal)

Ways to make royal flush: 4 (one per suit)
Total 5-card combinations: 2,598,960

Probability: 4 / 2,598,960

Before any draw decisions

Optimal Strategy Odds

With correct hold/draw strategy:
Probability: 1 in 40,391

Much better than dealt!
Why? Drawing to royal parts

If dealt 4 to a royal:
47 cards, 1 completes royal
Much higher than 1 in 649,740

How Strategy Improves Odds

Dealt Q-J-10 suited:
Hold all three
Draw 2 cards

Probability to complete royal:
Need A and K of same suit
1/47 × 1/46 = 1 in 2,162

Still rare, but possible
Strategy creates opportunities

Small but critical piece

Expected Value Per Hand

$5 max bet, 1 in 40,391 odds:

Royal EV = ($4,000 - $5) × (1/40,391)
         = $3,995 / 40,391
         = $0.0989 per hand

About 10 cents per hand
From a rare event

Strategy Considerations

When to Break a Hand for Royal Draw

Dealt: Q-Q-J♠-10♠-9♠

Option A: Keep pair of queens
EV: ~0.82 units

Option B: Keep J-10-9 suited
EV: ~0.72 units
(Only 3 to a royal with gaps)

Keep the pair!
Don't chase royals incorrectly

Correct Royal Chasing

Dealt: K♥-Q♥-J♥-10♣-3♠

Option A: Keep K-Q-J (3 to royal)
EV: ~0.73 units

Option B: Keep K-Q-J-10 (straight draw)
EV: ~0.68 units

Keep 3 to royal!
Give up open-ender for royal potential

Four to a Royal

Dealt: A♠-K♠-Q♠-J♠-7♣

ALWAYS keep 4 to royal
Break any hand for this

EV of 4 to royal: 47.87 units
Even break full house (9 units)
This is automatic

Real-World Examples

Example 1: Royal Flush Hit

You're dealt K♦-Q♦-J♦-10♦-3♥:

Hold: K-Q-J-10 diamonds
Draw: 1 card

Need A♦: 1 in 47 chance (2.13%)

Result: A♦ appears!
Royal flush!
Payout: 4,000 coins

This is the dream scenario
Happens 1 in 40,391 hands overall

Example 2: Time Between Royals

Playing 500 hands per hour at $1 max ($5/hand):

Expected hands between royals: 40,391
Hours of play: 40,391 / 500 = 80.8 hours

Wagered between royals: 40,391 × $5 = $201,955
Expected loss at 0.46% edge: $929

Hit royal: +$4,000
Net over cycle: +$3,071

BUT: Variance is enormous
Could go 100+ hours without

Example 3: Session Without Royal

8-hour session, no royal flush:

Hands played: 4,000
Wagered: $20,000

Expected royals: 4,000 / 40,391 = 0.099
About 10% chance of hitting royal

Expected non-royal return: 97.56%
Non-royal winnings: $19,512
Difference: -$488

Normal session without royal
Grinding other hands

Example 4: Max vs Non-Max Comparison

Same 40,391 hands, different bet levels:

Max bet ($5):
Wagered: $201,955
Expected return: $201,028
One royal: +$4,000
Net: +$3,073

1-coin bet ($1):
Wagered: $40,391
Expected return: $39,422
One royal: +$250
Net: +$281

Max bet captures 10× more value from royal

Common Mistakes

1. Playing Non-Max Bet

Mistake: "Save money, bet less" Problem: Royal pays 250:1 instead of 800:1 Fix: Always max bet or lower denomination

2. Breaking Strong Hands for Royals

Mistake: Break two pair for 3 to a royal Problem: Gives up more EV than gains Fix: Follow proper strategy

3. Expecting Royals Regularly

Mistake: "Due for a royal after 20,000 hands" Problem: Each hand is independent Fix: Understand variance, build bankroll

4. Underestimating Variance

Mistake: $500 bankroll for $1 video poker Problem: Royals are too rare to rely on Fix: 10,000+ hand bankroll recommended

No. Drop to a lower denomination and max bet. The 250:1 non-max payout destroys your expected value.
